To calculate the electromotive potential, also known as potential of the electromotive force (EMF), of a galvanic, or voltaic, cell using the E Cell formula when calculating E Cell: 1. Split the equation into half reactions if it isn't already. 2. Determine which equ...
Calculate the equivalent resistance. For the circuit below, calculate the equivalent resistance. Find the equivalent resistance between A and B in the circuit. What is the equivalent resistance of the given circuit? How to find equivalent resistance in complex circuits? Calculate the equivalent resista...
In a no load condition, you can use the motor’s KV value to estimate the motor’s speed based on the voltage delivered. As discussed in our article on how to calculate motor KV, we can replace Back EMF with input voltage in this equation to estimate the rotation speed of our electric...
If it's rechargeable, then it will have a shortened life, because a 1.8Ahr capacity is far from optimal for a load of more than an amp.FAQ: How can I calculate the time it would take for my battery to run down? How long does a battery last on average?
The best approach is to calculate the ON/OFF time of the transistor which yields maximum stable voltage across the output, meaning we need to make sure that the inductor is optimally switched such that it’s neither switched ON too quickly which might not allow it to discharge optimally, and...
How to Calculate KVA From The Electric Bill. Utility companies charge per kilowatt hour or KWh. However, the electrical system in your home represents an electrical load to the utility company and that load is a drag on the total power delivered to your
Learn what membrane potential is and how it differs from resting membrane potential. Calculate membrane potential using the membrane potential equation and examples. Related to this Question How does increasing the concentration of one ion influence the current and driving force of anoth...
of the battery. (ii)Calculate resistivity of potentiometer wire if length of wire is 100 cm and area of cross-section (initially) is 100cm2. View Solution Passage - II : Consider a potentiometer arrangement having auniform wire AB of resistance 99Ω A driving battery of 10V emf and ...
This is the acoustical part of how to calculate decibels. It describes the sound pressure, since SPL means sound pressure level. This is somewhat related to the voltage ratios. Another term for voltage is electromagnetic force, or EMF. The force of air pressing against the resistance of the ...
of ions on each side of a membrane. The Goldman Equation includes other factors like the permeability of the cell membrane and the type of transfer across the surface to calculate this potential. When these cells reach equilibrium then the it's membrane potential is equal to the Nernst ...
